I recently got a bag like that on eBay for my T660 turbo touring, came with a factory tool kit!
Reading through this thread brought me back to my fan cooled days... I had a 1988 AFS Cougar 500 fan with the outboard rear shocks! I actually have a 500 fan engine sitting on a shelf in the garage that would probably start right up if it had a sled to belong to.
Great to read about all your work 👍
